Hi all,
My Drayton thermostat relay gave up last month, while I waited for the landlord to finally send an electrician to replace it, the plumber put a manual function on my vaillant ecotec pro. So I could put the heating on, then to turn it off drop the temperature until the boiler entered summer mode. Can anyone tell me how to switch this function off so it comes on when the thermostat demands heat.
Thanks in advance, really don't want to wait another week or 2 for someone to come round to sort a 2 minute job.
